本發明係提供一種拼接式多角度色彩導表製作方法，尤指可利用複數拼片列印時面向不同角度，並與主體拼接組裝成一共平面之3D色彩導表，便可使用色彩量測儀器量測表面上個別色塊的色度值作為色彩校正，以及分析3D列印模型各個方向或角度色差的依據。 The invention provides a splicing multi-angle color guide table manufacturing method, in particular, a color measuring instrument can be used, which can be assembled into a coplanar 3D color guide table by using a plurality of splicing faces facing different angles and being assembled with the main body. The chromaticity values of the individual patches on the surface are measured as color correction, and the basis for analyzing the chromatic aberration of the 3D printing model in all directions or angles.
按，色彩與影像科技是一門跨領域的人因應用科學，過去被視為藝術的一環，但近年來受到各領域的高度重視，除了廣泛地被應用在一般傳統產業以外(如印刷、油漆、紡織、食品與美容等)，並在新興產業中扮演了技術突破的關鍵角色，包括影像技術、光電、多媒體、照明科技、文創設計等領域，而隨著色彩與製程技術不斷提升，便有業界開發3D列印技術，以因應立體印刷產業之轉變。 Press, color and imaging technology is a cross-disciplinary application of human science. In the past, it was regarded as a part of art, but in recent years it has been highly valued in various fields, except that it is widely used in general industries (such as printing, painting, Textiles, food and beauty, etc., and play a key role in technological breakthroughs in emerging industries, including imaging technology, optoelectronics, multimedia, lighting technology, cultural and creative design, and with the continuous improvement of color and process technology, The industry develops 3D printing technology to cope with the transformation of the three-dimensional printing industry.
再者，目前3D列印技術大多為單色，並需要重複加工、製程較為繁複，成品多為粗糙產品，因此3D列印技術將朝向多色列印整合性製程，並結合立體影像的處理技術，以節省生產成本，而傳統之平面印刷主要利用具有四個印刷單元色座的印刷機分別對紙張進行彩色印刷，其四個印刷單元色座上分別具有青色(C)、洋紅色(M)、黃色(Y)與黑色(K)不同的顏色，由於彩色印刷時顏色的色均有可能會不一致， 所以一般皆會利用色彩導表用於控制上述之印刷輸出設備形成相同於印刷之色彩及明度，惟隨著現今印刷產業因數位化設備導入的影響，並為了滿足客戶需求多樣化、印刷流程複雜化等因素，使得印刷技術也由以往的平面影像印刷發展出3D列印之全彩印刷技術，且因一般色彩導表無法測試3D列印時之色彩資訊，以致使彩色印刷時顏色的色均有可能會不一致，因此需要製作出一種3D色彩導表，以測試3D列印模型在不同方向或角度平面上的顏色表現作為色彩校正，藉此確保3D列印時色彩之準確度，便為從事於此行業者所亟欲研究改善之關鍵所在。 Furthermore, most of the current 3D printing technologies are monochrome, and require repeated processing and complicated processes. The finished products are mostly rough products. Therefore, the 3D printing technology will be directed to multi-color printing integrated processes, and combined with stereo image processing technology. In order to save production costs, the conventional flat printing mainly uses a printing machine with four printing unit color seats to respectively color the paper, and the four printing unit color seats have cyan (C) and magenta (M) respectively. , yellow (Y) and black (K) different colors, color may be inconsistent due to color printing, Therefore, the color guide table is generally used to control the above-mentioned printing output device to form the same color and brightness as the printing, but with the influence of the introduction of the current printing industry factorization device, and in order to meet the diversified customer needs, the printing process is complicated. Factors such as the development of printing technology have also developed 3D printing full-color printing technology from the past flat-panel printing, and because the general color guide can not test the color information of 3D printing, so that the color of the color during color printing It may be inconsistent, so you need to create a 3D color guide to test the color performance of the 3D printing model in different directions or angle planes as color correction, thereby ensuring the accuracy of color in 3D printing. The key to this industry's desire to study improvement.

An image, and the first butt joints 12 of the intermediate layer at the periphery of the main body 1 respectively have a plurality of first buckles 121 and a first buckle groove 122 arranged at different distances, and cooperate with the second layer of the middle layer of the patch 2 The second butting portion 221 and the second protruding portion 222 of the intermediate layer of the mating surfaces of the two adjacent tiles 2 are not equidistant from the fourth butting portion 24 The plurality of third buckles 231, the third fastening slots 232, the fourth fastening slots 241 and the fourth protruding buckles 242 arranged in the offset interval can be assembled and assembled by complementary fitting and clamping, and the user is assisted by the user 2 to the patch 2 and the main body 1 Quickly splicing to the correct position, to avoid the misspelling effect of the patch 2 position, and to have a foolproof effect, more competitive products.
而拼接式3D色彩導表於組合後，可使主體1之第一影像層11與複數拼片2之第二影像層21上所陣列分佈之每個色塊111、211大小與間距皆相同，讓使用者能夠使用半自動或自動色彩量測儀器進行逐行掃瞄量測或定位量測，以量測出3D色彩導表頂層與底層表面上個別色塊111、211的色度值(如顏色之光譜反射率等色彩資訊)，並由該等色塊111、211的色度值可測試3D列印模型在不同方向或角度平面上的顏色表現並作為色彩校正，以及分析3D列印模型各個方向或角度色差的依據，藉此確保3D列印時色彩之準確度與品質。 After the splicing 3D color guides are combined, the size and spacing of each of the color patches 111 and 211 distributed on the array of the first image layer 11 of the main body 1 and the second image layer 21 of the plurality of tiles 2 are the same. Allows the user to perform a progressive scan or position measurement using a semi-automatic or automatic color measurement instrument to measure the chromaticity values (such as color) of the individual patches 111, 211 on the top and bottom surfaces of the 3D color guide Color information such as spectral reflectance), and the chromaticity values of the color patches 111, 211 can test the color representation of the 3D printing model in different directions or angle planes and serve as color correction, and analyze each of the 3D printing models. The basis of the directional or angular chromatic aberration to ensure the accuracy and quality of the color when printing in 3D.
再者，色彩量測儀器量測到3D色彩導表中各種代表不同角度的色塊111、211之色度值有很多種分析與比較方式，若是以向 上平放的面作為基準時，可個別比較出不同角度的色塊111、211之平均色差，如3D色彩導表經過鹽水後處理，並在D50主要供判別色彩用途的光源下，可得知以向下之負Z方向與斜上方向之X+Z、Y+Z方向所造成的色差將影響最大，該色差中又以明度差的影響最大，藉由分析不同方向或角度的色差，可輔助建構3D列印色彩管理系統時能夠對不同方向的色差作色彩校正。 Furthermore, the color measuring instrument measures various chromaticity values of the color patches 111, 211 representing different angles in the 3D color guide table, and has a plurality of analysis and comparison methods. When the upper flat surface is used as a reference, the average color difference of the color patches 111 and 211 at different angles can be individually compared, for example, the 3D color guide is processed by the salt water, and the D50 is mainly used for determining the color use. The color difference caused by the downward negative Z direction and the obliquely upper direction of X+Z and Y+Z directions will have the greatest influence, and the chromatic aberration is most affected by the brightness difference, by analyzing the chromatic aberration of different directions or angles. Auxiliary construction of the 3D printing color management system enables color correction of chromatic aberrations in different directions.
而3D列印不同的墨水，可能也會在列印不同方向的面時因為材料特性造成不同的影響，如黑色可能因為由青色、洋紅色、黃色三種墨水混合的關係，所以造成有最大的色差；另，3D色彩導表後處理的方式有很多種，也可以比較不同後處理方式所得到的色域大小，如紅色、綠色、藍色三原色(RGB)以不同比例相加所得到的青、洋紅、黃、黑、紅、綠、藍，並在D50光源下無後處理、鹽水後處理、蠟後處理的3D色彩導表列印色所繪製出的色域箭圖，可個別比較出不同後處理方式的色彩表現，所以在建構3D列印色彩管理系統的時候，就需要為各種不同的後處理方式進行專屬的色彩管理。 3D printing different inks may also have different effects on the surface of different directions due to material properties. For example, black may have the largest color difference due to the mixing of three inks of cyan, magenta and yellow. In addition, there are many ways to post-process the 3D color guide. You can also compare the color gamut obtained by different post-processing methods. For example, the red, green, and blue primary colors (RGB) are added in different proportions. Magenta red, yellow, black, red, green, blue, and the color gamut arrow drawn by the 3D color guide printing color without post-treatment, salt water post-treatment, and wax post-treatment under D50 light source, can be compared differently The color performance of the post-processing method, so when constructing the 3D printing color management system, it is necessary to carry out exclusive color management for various post-processing methods.
